HEATER FOR STOCKWATERING T'ROUGHS.

SPEEFCATON forming part of Letters Patent No. 398,052, dated February19, 1889. Application tiled March 21, 1888. Serial No. 267,959. (Nomodel.)

vented a new and useful Improvement in g' Heaters for Stock-XVateringTroughs, of which the following is a specification.

Gurinvention relates to animprovementin water-heaters; and it consistsin the peculiar construction Iand combination of devices, which will bemore fully set forth hereinafter; and particularly pointed out in theclaim.`

In the accompanying drawings, Figure l is a vertical longitudinalsectional view of a water-heater embodying our improvements. Fig. 2 is ahorizontal sectional view of the saine, taken on the line o a of Fig. l.

A represents a vertical cylindrical vessel, which is provided on itslower side with supporting-feet ll, of suitable depth. Communicatingwith one side of the vessel -near the lower end thereof, is a verticalpipe, C, the upper end of which extends somewhat above the top of thevessel, and is adapted to be closed or uncovered by a stopper or plug,D. From one side of the vessel A, near the lower end thereof, extends ahorizontal cylindrical tlue, E, the inner end of which is open andcommunicates withthe vessel A, and the outer end of which is closed.From the underside of the outer end of the cylindrical flue E depends asupporting foot and standard, F, and from the upper side of the saidcylindrical fine Il, at the outer end thereof, extends a verticalsmoke-pipe, G, of suitable height. In the upper end of the smoke-pipe isarranged the spark-arrester H, which comprises a pair of cones, I K,which are made of wire-cloth or other suitable perforated material, andhave their bases provided with collars L M, respectively, said collar Lbeing of less diame# ter than the collar lWI and fitting snugly therein.The collar lll tits snugly in the upper end of the smoke-pipe, and fromsaid collar rises a pair of standards, N, which support a coneshapedcap, O.

P represents a steam or water conducting pipe, which extends entirelythrough the cylindrical flue E, has its outer end projecting through theclosed end of said flue, and has its inner end extended downward throughthe bottom of the vessel A. The outer end of the pipe P is provided witha screw-coupling, R, by means of which a stean'i-pipe, S, may beconnected thereto or disconnected therefrom.

T represents a portable firebox, which is adapted to fit in the vesselA, and is in the form'of a truncated cone, t-he upper end of saidfire-box being nearly equal in diameter to the dian'ieter of the vesselA, and being adapted to iit snugly therein, so as to support the saidportable lire-box in the vessel A, with the bottom and sides of thefire-box out .of contact with the bottom and sides of the vessel. In onesido of the fire-box, near the bottom thereof, are a series of openings,U,

and in the opposite side thereof, in line with the openings U, is anopening, V, of suitable size. The said tire-box is provided at its upperedge, on opposite sides, with ears lV, to

which is connected a bail or handle, X, by

means of which the fire-box may be removed from the vessel A or placedtherein.

4Y represents a cover or top which is adapted to close the upper end ofthe fre-box, is provided with an opening, Z, and has a slide, A', whichis pivoted to the cover or top and is adapted to cover or uncover theopening Z.

Our invention is particularly designed for heating water in troughs tobe used for scalding-hogs or mixing with feed for cattle and l horses,and is also designed for use in generating steam for cooking' feed forlive stock, and the operation thereof is as follows:

The vessel A, together with the cylindrical Hue E, are placed in atrough of water at such a depth that the flue E is entirely or partiallysubmerged, so that the outer end of the pipe P is beneath the level ofAthe water. The fire-box is then suspended .in the vessel A, and isarranged in such a position that its openings U are opposite the lowerend of the pipe C and the opening V is opposite the inner end of theflue E. A fire is built in the fire-box, the cover placed thereon, andthe stopper or plug D removed from the upper end of pipe C. A current ofair then passes downward through the pipe C, enters the vessel A, andpasses through the fire-box over and through the fuel, so as to promotecome bustion, and the smoke and products of coinbustion pass through theopening V of the fire-box into the cylindrical flue E and escape fromthence through the smoke-pipe G and the spark-arrester Il. The vessel Ais heated by radiation from the lire-box, and the iiue or tube E isheated by the products of combustion and flames passing through thesame, and, inasmuch said vessel A and tube or iiue are partiallysubmerged, it follows that the water in the trough will speedily becomeheated thereby. inasmuch as the tube P communicates at `both ends withthe water, the said tube is constantly Iilled therewith,

and as the said tube extends through the tubular flue E the watertherein becomes intensely heated and escapes into the troilgh, and itsplace is instantly supplied by the water from the trough, and thus aconstant circulation of water is maintained, and the water in the troughis as speedily reduced to the same temperature. Then the water in thetrough has become sufficiently heated, the heater is removed therefrom.A

Then itis desired to generate steam, the heater is placed in the trough,as before described, a iire started therein, and the steampipe S iscoupled to the outer end of the pipe P, and the outer end of said pipe Pis raised above the level of the water in the trough. By this means thewater in the lower portion oi' pipe P is rapidly converted into steam,which escapes through the pipe S and is discharged at the desired pointwhere the steam is to be used, and as fast as the water in the lower endof pipe P is converted into steam its place is supplied by water fromthe trough, as will be readily understood.

As the smoke and products of combustion ascend through the smokepipe GrVthey strike against the lower perforated cone, I, which serves to arrestthe sparks and causes them to drop into the lower side of the tube E.Any sparks which may pass through the meshes of the lower cone with thesmoke and products of combustion will be arrested by the upper cone, K,and caused to drop into the lower cone. W'hen it is desired to clear thesparkarrester ot the accumulated cinders, the sparkarrester is removedfrom the upper end of the smoke-pipe, and the lower cone, I, is removedby withdrawing its collar L from the collar lll 1When it is desired toprevent too active combastion of the fuel in the iii,ebox,tl1is maybeaccomplished by turning the iire-box in the vessel A so that itsopenings U V will be out of line with the openings at the inner ends ofpipe C and tubular flue E, the cect of this arrangen'ient oi. thefire-box being to reduce the draft therethrough.

It will be observed that the vertical cylindrical vessel A has anentirely unobstructed interior, so that the iire-box can be readilyplaced therein, and by employing the portable fire-box we are not onlyenabled to regulate the draft at will by shifting the position of thelire-box, but we also preserve the vessel A, as the fire is out ofcontact with the said vessel and consequently cannot burn through andwear away the same. Furthermore, it will be observed that the draftcarries the heat directly along the pipe P, so that the said pipe willbe subjected to the action ot the heat for a considerable period et'time, and the said pipe extends through the bottom of the vesselA theWaterwill be admitted close to the iire-box,where the heat is greatest,and then carried through the iiue E in a` line parallel with the lineof. draft, so as to obtain the full benefit of the heat.

Having thus described our invention, we claim rlhe improved heater forstock -watering troughs, consisting of the vertical cylindrical vesselA, the vertical iiue C, and the horizontal flue E, communicatingtherewith at diametrically-opposite points near the bottom thereof, andthe smoke-flue leading upward from the end of the flue E, the lire-boxremovably supported in the vessel A and having diametrically-oppositeopenings in its sides near its lower end, and adapted to be turned so asto, bring'said openings into or out of line with the hue E, and the pipeP, havingv one end extending through the bottom et the vessel A, thenceextending vertically upward to near the fire-box,y and thencehorizontally through the flue E and projecting through the end of thesame, as specified.

In testimony that we claim the foregoing aS our own we have heretoaffixed our signatures in presence of two` witnesses.
